Description

Technical Field

[0001] This utility model relates to the field of electromechanical installation device technology, specifically an electromechanical installation device for water conservancy and hydropower projects. Background Technology

[0002] Hydraulic and hydropower engineering primarily studies the basic knowledge and skills related to water resources, hydraulic structures, hydraulics and fluid dynamics, and hydraulic engineering technology. It involves the surveying, planning, design, construction, and management of hydraulic and hydropower projects. Examples include the planning of the South-to-North Water Diversion Project, the construction of hydraulic structures such as hydropower stations, dams, and sluice gates, and the design of river management projects. Mechanical and electrical equipment generally refers to machinery, electrical appliances, and electrical automation equipment. In construction, it often refers to a general term for machinery and piping equipment excluding those used in earthwork, carpentry, steel reinforcement, and masonry work.

[0003] A search revealed a Chinese patent publication number (CN 220615878 U) disclosing an electromechanical installation device for water conservancy and hydropower projects, relating to the field of water conservancy and hydropower engineering technology. The device includes a base, with a first protective plate fixedly connected to one side of the upper part of the base, and second protective plates fixedly connected to the other two sides of the upper part of the base. Each of the second protective plates contains fasteners for fixing electromechanical equipment. A push-pull rod is fixedly connected to the outer side of the first protective plate, and casters are fixedly connected to the four corners of the lower part of the base. The first and two second protective plates form a semi-enclosed protective measure for the electromechanical equipment. A first adjusting handle can drive a corresponding one-way screw to rotate. Since the one-way screw is threadedly connected to the support plate, its rotation causes a top block to move closer to or away from the electromechanical equipment on the base. The top block abuts against the side wall of the electromechanical equipment, thereby improving the safety of the equipment during transportation or installation and minimizing the risk of the equipment falling off the base.

[0004] The installation device in the aforementioned patent still has some shortcomings. The installation of existing generator stators mostly involves hoisting them onto a transfer vehicle using a crane and then pushing them for installation. However, conventional transfer vehicles only serve to support the transfer and cannot adjust the height of the stator to be installed. This necessitates subsequent mechanical operations for installation, increasing the difficulty of installing the electromechanical stator and making it inconvenient for users. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an electromechanical installation device for water conservancy and hydropower projects. It solves the problem that the installation of stators for existing generator sets mostly involves hoisting them onto a transport vehicle using a crane and then pushing them for installation. However, conventional transport vehicles only serve to support and move the stator, making it difficult to adjust the height of the stator to be installed. This necessitates subsequent mechanical operations, increasing the difficulty of installing the electromechanical stator and making it inconvenient for users.

[0006] This utility model provides the following technical solution: an electromechanical installation device for water conservancy and hydropower projects, including a transfer support platform, bottom support legs evenly arranged around the bottom of the transfer support platform, movable wheels installed at the bottom of the bottom support legs, a stator fixing assembly provided at the top of the transfer support platform, a motor stator body provided on the stator fixing assembly, a stator auxiliary installation assembly provided at the bottom of the transfer support platform, and a push handle provided on the side of the transfer support platform;

[0007] The stator fixing assembly includes a fixing connecting plate disposed at the top of the transfer support platform. The top of the fixing connecting plate is provided with a fixing mounting groove, and the middle of the fixing mounting groove is provided with a central through hole. The inner wall of the fixing mounting groove is evenly provided with abutment plates around its perimeter. The side of the abutment plate is rotatably connected with an abutment screw, and the end of the abutment screw is threaded through the side wall of the fixing connecting plate.

[0008] The stator auxiliary installation assembly includes a lifting through hole at the top of the transfer support platform. A bottom connecting frame is provided at the bottom of the transfer support platform. A drive motor is installed at the bottom of the bottom connecting frame. A lifting screw is rotatably mounted on the bottom connecting frame. The top of the lifting screw is rotatably connected to the bottom of the transfer support platform. The drive shaft of the drive motor rotates through the bottom connecting frame and is fixedly connected to the bottom of the lifting screw. A lifting sleeve is fitted on the lifting screw. Two push support rods are symmetrically and vertically arranged at both ends of the lifting sleeve.

[0009] Preferred technical solution 1: Two limiting through holes are symmetrically opened on both sides of the bottom wall of the lifting through hole, the top end of the pushing support rod passes through the limiting through holes, and a fixing connecting piece is fixed to the top end of the pushing support rod.

[0010] Preferred technical solution 2: A pushing disk is provided inside the lifting through hole, and the top end of the fixed connecting piece is fixedly connected to the bottom end of the pushing disk.

[0011] Preferred technical solution 3: The inner sidewall of the contact plate is in the shape of a curved arc that fits against the outer side of the motor stator body.

[0012] This design allows the motor stator body to be placed in a fixed mounting slot, making it more stable under the contact of the contact plate.

[0013] Preferred technical solution four: A rotating block is provided at the end of the contact screw.

[0014] This solution makes it easier for users to rotate the contact screw.

[0015] Preferred technical solution five: The diameter of the pushing disk is smaller than the opening diameter of the central through hole.

[0016] This design enables the pusher disc to pass through the central through-hole and lift the bottom of the motor stator body under the push of the fixed connecting piece.

[0017] Compared with the prior art, this utility model provides an electromechanical installation device for water conservancy and hydropower projects, which has the following beneficial effects:

[0018] (1) This utility model provides a stator fixing assembly and a stator auxiliary installation assembly on a transfer support platform. The stator fixing assembly has a fixing mounting groove in the fixing connecting plate. The fixing mounting groove is fixed to the side wall of the motor stator body by a contact plate, which ensures the stability of the motor stator body during installation and transfer. The push disc in the stator auxiliary installation assembly can be driven by the drive motor to the lifting screw, so that the lifting screw drives the push support rod to push the bottom of the push disc through the lifting screw sleeve, pushing the motor stator body upward and moving it into the stator installation compartment for installation. In this process, the user does not need to use other machinery to lift the motor stator body again, making the installation and transfer of the motor stator body more convenient, simple to operate, and more convenient to use.

[0026] Please see Figure 1-4 ,

[0027] Example 1: An electromechanical installation device for water conservancy and hydropower projects includes a transfer support platform 1, bottom support legs 2 are evenly arranged around the bottom of the transfer support platform 1, a movable wheel 3 is installed at the bottom of the bottom support legs 2, a stator fixing assembly 4 is provided at the top of the transfer support platform 1, a motor stator body 5 is provided on the stator fixing assembly 4, a stator auxiliary installation assembly 6 is provided at the bottom of the transfer support platform 1, and a push handle 7 is provided on the side of the transfer support platform 1.

[0028] The stator fixing assembly 4 includes a fixing connecting plate 401 disposed at the top of the transfer support platform 1. The top of the fixing connecting plate 401 is provided with a fixing mounting groove 402. The middle of the fixing mounting groove 402 is provided with a central through hole 403. The inner wall of the fixing mounting groove 402 is evenly provided with abutment plates 404. The side of the abutment plate 404 is rotatably connected with an abutment screw 405. The end of the abutment screw 405 is threaded through the side wall of the fixing connecting plate 401.

[0029] The stator auxiliary installation assembly 6 includes a lifting through hole 601 at the top of the transfer support platform 1. A bottom connecting frame 602 is provided at the bottom of the transfer support platform 1. A drive motor 603 is installed at the bottom of the bottom connecting frame 602. A lifting screw 604 is rotatably provided on the bottom connecting frame 602. The top of the lifting screw 604 is rotatably connected to the bottom of the transfer support platform 1. The drive shaft of the drive motor 603 rotates through the bottom connecting frame 602 and is fixedly connected to the bottom of the lifting screw 604. A lifting sleeve 605 is sleeved on the lifting screw 604. Two push support rods 606 are symmetrically and vertically arranged at both ends of the lifting sleeve 605. Two limiting holes 607 are symmetrically opened on both sides of the bottom wall of the lifting through hole 601. The top of the push support rod 606 passes through the limiting hole 607. A fixing connecting piece 608 is fixedly fixed to the top of the push support rod 606. A push disc 609 is provided in the lifting through hole 601. The top of the fixing connecting piece 608 is fixedly connected to the bottom of the push disc 609.

[0030] Example 2: The difference between this example and Example 1 is that the inner wall of the contact plate 404 is a curved arc shape that fits against the outer side of the motor stator body 5.

[0031] This makes the motor stator body 5 placed in the fixed mounting slot 402 more stable under the contact plate 404.

[0032] Example 3: The difference between this example and Example 1 is that a rotating block is provided at the end of the contact screw 405.

[0033] This makes it easier for users to rotate the contact screw 405.

[0034] Example 4: The difference between this example and Example 1 is that the diameter of the pushing disk 609 is smaller than the opening diameter of the central through hole 403.

[0035] This allows the pusher disc 609 to pass through the central through hole 403 and lift the bottom of the motor stator body 5 under the push of the fixed connecting piece 608.

[0036] In this embodiment, the installation of existing generator stators is mostly carried out by hoisting them onto a transfer vehicle with a crane and then pushing them for installation. However, conventional transfer vehicles only serve to support the transfer and cannot adjust the height of the stator to be installed. This requires subsequent mechanical operation for installation, which increases the difficulty of installing the electromechanical stator and makes it inconvenient for users.

[0037] In summary, in specific implementation, when the user needs to transfer and install the motor stator body 5, the user can first use a crane to hoist the motor stator body 5 into the fixed mounting slot 402 in the stator fixing assembly 4. By rotating the abutting screw 405, the abutting screw 405 pushes the abutting plate 404 to abut and fix the side wall of the motor stator body 5.

[0038] Next, by pushing the push handle 7, the motor stator body 5 fixed in the stator fixing assembly 4 on the transfer support platform 1 is moved to the installation position of the motor stator body 5. At this time, the user can rotate the abutment screw 405 so that the abutment plate 404 no longer abuts against the side wall of the motor stator body 5. By connecting the drive motor 603 in the stator auxiliary installation assembly 6 to start, the drive motor 603 can drive the lifting screw sleeve 605 to move upward through the lifting screw 604. Two push support rods 606 are symmetrically arranged on both sides of the lifting screw sleeve 605.

[0039] The top of the push support rod 606 passes through the limiting through hole 607. The top of the push support rod 606 is connected to the push disc 609 through the fixed connecting piece 608, so that the push disc 609 is pushed upward. In turn, the push disc 609 can pass through the central through hole 403 and push the bottom end of the motor stator body 5 placed in the fixed mounting slot 402 upward, so that the motor stator body 5 can be installed more accurately and conveniently into the mounting compartment. In this process, the user does not need to use other machinery to lift the motor stator body 5 again, making the installation and transfer of the motor stator body 5 more convenient, simple to operate, and more convenient to use.
